I.     RAW  MATERIALS  CHIEFLY  VALUABLE  FOR 
NITROGEN. 

NITRATE  OF  SODA,  OR  SODIUM  NITRATE. 

As  offered  in  the  Connecticut  market  this  year,  nitrate  of  soda 
has  contained  an  average  of  15.44  per  cent,  of  nitrogen,  equivalent 
to  93.6  per  cent,  of  pure  sodium  nitrate. 

The  following  nine  samples  were  analyzed:

The  cost  of  nitrogen  in  nitrate  of  soda  in  small  lots  at  retail  has  been 
on  the  average  26  cents  per  pound,  1  1-2  cents  more  than  last  year,  and 
9  or  10  cents  more  than  in  1915. 


376  CONNECTICUT   EXPERIMENT   STATION   BULLETIN    204.  ^ 

The  supply  has  been  so  small,  however,  and  the  rise  in  price  as 
the  season  advanced  has  been  so  rapid  that  average  figures  have 
little  significance. 

COTTON  SEED  MEAL. 

Ninety-five  samples  of  this  material,  bought  for  use  as  a  ferti- 
lizer, have  been  tested.    Most  of  the  samples  represent  car  lots. 

Of  the  69  samples  which  came  to  the  laboratory  with  guaranties, 
26  contained  the  claimed  amount  of  nitrogen  and  reqtdre  no  de- 
tailed report  here.  On  the  other  hand,  43,  or  62  per  cent,  of  the 
guaranteed  samples,  were  deficient  in  nitrogen.  The  analyses  of 
these  samples  are  given  in  the  table. 

The  deficiencies  were  not  quite  so  great  in  amotmt  as  last  year 
ranging  from  o.io  to  0.8I  per  cent.,  with  an  average  in  the  43 
samples  of  0.30  per  cent.  Based  on  the  average  cost  of  nitrogen 
in  cotton  seed  meal,  as  determined  below,  these  deficiencies  would 
warrant  a  rebate  of  from  53  cents  to  $4.29  per  ton,  a  considerable 
item  when  the  meal  is  piirchased  in  car  lots. 

The  ninety -five  samples  contained  from  5.37  to  7.20  per  cent, 
of  nitrogen,  with  an  average  of  6.10  per  cent.  The  average  cost 
per  ton,  in  the  79  samples  where  the  price  was  furnished,  was 
$44.20,  about  $5.50  higher  than  last  year. 

Assuming  2.9  and  1.9  as  the  respective  percentages  of  phosphoric 
acid  and  potash  in  the  meal,  if  they  are  valued  at  4  cents  and  25  cents 
per  pound,  respectively,  the  nitrogen  of  cotton  seed  meal  in  the  ninety- 
five  samples  cost  on  the  average  26.5  cents  per  pound,  5.6  cents  higher 
than  last  year.    This  is  equivalent  to  $5.30  per  unit. 

Most  of  the  purchasers  report  that  where  the  nitrogen  in  the 
meal  was  less  than  guaranteed  they  had  little  difficulty  in  securing 
rebates. 

In  our  judgment  the  rebates  did  not  fully  compensate  for  the 
deficiency  where  not  more  that  $4.00  per  unit  was  allowed.  Cer- 
tainly, at  present  prices  of  meal,  $5.30  per  unit  is  none  too  high 
a  rebate.

CASTOR  POMACE. 

This  is  a  residue  from  the  manufacture  of  castor  oil  and  is  used 
chiefly  as  a  tobacco  fertilizer.  Experience  indicates  that  it  is  a 
little  slower  in  its  action  than  cotton  seed  meal  and  that  it  gives 
a  somewhat  heavier  quality  to  the  tobacco  leaf.  Stock  will  eat 
it  greedily  if  they  have  the  chance,  but  it  is  extremely  poisonous.

In  sample  9350  one  per  cent,  each  of  phosphoric  acid  and  potash 
was  guaranteed;  the  sample  contained  1.46  per  cent,  of  phos- 
phoric acid  but  only  0.45  per  cent,  of  water-soluble  potash. 

Sample  8871  was  1.55  per  cent,  deficient  in  nitrogen. 

The  average  nitrogen  content  of  the  samples  was  4.60  per  cent, 
and  the  average  cost  per  ton,  $31.28. 

Assuming  a  value  of  4  cents  per  pound  for  phosphoric  acid  and  25 
cents  per  pound  for  potash,  the  average  cost  of  nitrogen  per  pound  in 
castor  pomace  this  year  was  27.3  cents,  or  $5.46  per  unit.

BASIC  LIME  PHOSPHATE. 

Shipments  of  basic  phosphate  from  abroad  have  been  almost 
cut  off  on  account  of  the  war.  As  a  substitute  for  basic  phosphate 
a  product  called  "basic  lime  phosphate"  has  been  put  on  the  mar- 
ket, of  which  we  have  analyzed  four  samples  of  two  brands. 
"Available  phosphoric  acid"  was  determined  by  the  so-called 
Wagner  method.

One  sample  of  each  brand  contained  less  "available"  phosphoric 
acid  than  v^as  guaranteed. 

PRECIPITATED  BONE  PHOSPHATE. 

This  is  a  manufacturing  by-product  and  consists  of  fine  precipi- 
tated phosphate  of  lime,  neutral  in  reaction,  and  contains  no 
nitrogen.  It  is  very  readily  soluble  in  ammonium  citrate  solution 
and  is  quickly  available  to  crops.  It  is  at  present  chiefly  used  as 
a  tobacco  fertilizer. 

Six  samples  were  analyzed,  all  of  which  were  sold  by  Olds  and 
Whipple,  Hartford.  9371  was  sampled  by  the  Station  at  the 
factory,  and  9373  by  the  Station  from  the  stock  of  F.  T.  Phelps, 
Suffield;  8711,  8712  and  8742  were  sampled  and  sent  by  the 
seller;  8872  was  sampled  and  sent  by  Karl  C.  Kulle,  Suffield. 
The  respective  car.ntimbers  for  the  last  .four  samples  were  88300, 
73792,  4822  and  73365- 

The  guaranty  for  the  material  was  28  per  cent,  "available"  and 
32  per  cent,  total  phosphoric  acid.

DISSOLVED  ROCK  PHOSPHATE  OR  ACID  PHOSPHATE. 

This  material  is  made  by  treating  mineral  phosphates  or  phos- 
phate rock  with  oil  of  vitriol  (sulphuric  acid) ,  which  converts  the 
larger  part  of  the  phosphoric  acid  into  forms  soluble  in  water,  and 
at  the  same  time  changes  into  sulphate  of  lime  a  large  part  of  the 
lime  which  was  previously  combined  with  phosphoric  acid. 

The  guaranty  usually  gives  the  percentage  of  "available"  phos- 
phoric acid.  This  is  only  a  trade  name  for  the  sum  of  the  water- 
soluble  and  citrate-soluble  phosphoric  acid.  Its  amotint  gives 
no  certain  indication  of  the  actual  availabliity  of  this  phosphoric 
acid  to  crops.  In  acid  phosphate,  however,  well  made  from 
domestic  rock,  it  is  fair  to  assiune  that  the  larger  part  of  the  "avail- 
able" is  also  agriculturally  available.

POTASH. 
Owing  to  the  war  very  little,  if  any,  potash  has  been  shipped  to 
this  country  during  the  past  three  years.  The  three  samples  of 
muriate  of  potash  analyzed  represented  stock  in  the  hands  of 
farmers  who  were  tempted  by  the  abnormally  high  prices  to  dis- 
pose of  their  surplus  stock.

FOR 


FISH  MANURES. 

The  twelve  samples  analyzed  show  considerable  uniformity  in 
the  content  of  nitrogen,  which  ranges  from  7.28  to  9.75  per  cent., 
with  an  average  of  8.34  per  cent.  The  phosphoric  acid,  however, 
shows  a  wide  range,  from  2. 75  to  10.41  per  cent.,  with  an  average 
of  6.77  per  cent.  Six  of  the  samples  failed  to  meet  their  guaranties, 
two  being  deficient  in  nitrogen,  one  in  phosphoric  acid,  and  three 
in  both  of  these  elements.  9365  and  9100  contained  only  about 
half  of  the  phosphoric  acid  guaranteed. 

The  average  cost  was  $53.44  per  ton,  about  $2  higher  than  last  year. 
If  the  phosphoric  acid  were  valued  at  4  cents  per  pound,  the  nitrogen  cost 
on  the  average  28.8  cents  per  pound;  if  at  6  cents  per  pound,  the  nitrogen 
cost  27.2  cents.

TANKAGE. 
(Analyses  on  pages  j86  and  387.) 

This  material,  made  fromi  the  waste  of  slaughter  houses  and  meat 
markets,  naturally  shows  considerable  differences  in  composition, 
depending  upon  the  relative  amounts  of  meat  and  bone  present. 

The  thirteen  samples  analyzed  fall  into  two  quite  well-defined 
groups,  the  one  containing  from  4.26  to  5.67  per  cent,  of  nitrogen 
and  from  14.06  to  21.42  per  cent,  of  phosphoric  acid,  the  other 
containing  from  7.16  to  8.34  per  cent,  of  nitrogen  and  from  5.62 
to  1 1. 1 9  per  cent,  of  phosphoric  acid. 

The  samples  of  the  first  group,  approximately  6-30  grade,  cost 
from  $28  to  $42  per  ton;  the  higher  grade  tankages,  9-20,  cost 
from  $48  to  $55  per  ton. 

The  average  composition  and  cost  of  the  two  grades  were  as 
follows :

Two  samples  failed  to  meet  their  nitrogen  guaranty,  one  that 
for  phosphoric  acid,  and  one  was  deficient  in  both  nitrogen  and 
phosphoric  acid.

BONE  MANURES. 
(Analyies  on  pages  j88  and  38Q.) 

The  analyses  of  twenty-one  samples  of  bone  are  given  in  the 
table.  "Bone,"  like  tankage,  has  a  wide  range  of  composition-, 
some  samples  being  from  raw  bone  with  or  without  much  adhering 
meat  and  cartilage,  others  representing  bone  which  has  been 
cooked,  the  grease  and  nitrogenous  matter  being  partially  removed. 

The  average  per  cent,  of  nitrogen  in  these  samples  is  3.40  and 
of  phosphoric  acid  23.35.  The  average  cost  per  ton,  barring  the 
exceptional  prices  of  9393  and  9387,  was  $40.60. 

Two  samples  failed  to  meet  their  nitrogen  and  two  their  phos- 
phoric acid  guaranties.

guaranteed  to  contain  four  per  cent,  of  potash,  though  only  one 
had  nearly  that  amount.  Seven  brands  guaranteed  3  per  cent., 
nineteen  2,  and  the  rest  i  per  cent,  or  less. 

Of  the  brands  containing  potash  about  23  per  cent,  failed  to 
meet  their  guaranty  in  one  ingredient,  while  of  the  172  without 
potash  16.8  per  cent,  failed  in  the  same  way. 

In  a  large  niimber  of  cases,  however,  a  shortage  of  one  ingredient 
was  made  good  by  an  overrun  of  another,  so  that  the  buyer  re- 
ceived full  value  for  his  money,  but  in  the  following  brands  this 
was  not  the  case.  Reckoning  nitrogen  at  27  cents,  available 
phosphoric  acid  at  6  and  potash  at  30  cents  per  pound,  respec- 
tively, the  deficiency  in  money  value  per  ton  was:

Quality  of  Plant  Food  in  Nitrogenous  Superphosphates. 

The  potash  given  in  the  analyses  is  all  water-soluble  and  avail- 
able to  crops. 

The  same  is  true  of  the  "soluble"  phosphoric  acid.  The  "citrate- 
soluble"  phosphoric  acid,  which  with  the  water-soluble  is  called 
"available"  by  trade  usage,  is  doubtless  more  promptly 
available  to  crops  than  the  insoluble,  although  there  are  probably

very  considerable  differences  in  the  agricultural  value  of  citrate- 
soluble  phosphoric  acid  from  different  sources  or  materials.  The 
same  is  true,  also,  of  insoluble  phosphoric  acid.  Thus,  the  insol- 
uble phosphoric  acid  of  bone  is  much  more  quickly  available  to 
crops  than  that  from  phosphate  rock  or  apatite. 

It  is  safest  to  give  preference  to  those  mixed  fertilizers  in  which 
the  proportion  of  insoluble  phosphoric  acid  is  small. 

Regarding  nitrogen,  that  which  is  in  form  of  nitrates  is  the

most  quickly  and  completely  available.  As  a  rule  the  nitrogen  of 
ammonia  salts  is  less  quickly  and  completely  available  than  that 
of  nitrates,  but  ranks  next  to  it. 

The  organic  nitrogen  of  fertilizers  is  supplied  by  a  great  variety 
of  materials  which  differ  very  considerably  in  agricultural  value. 

The  details  of  the  methods  used  to  detect  very  inferior  forms 
of  nitrogen  have  been  given  in  previous  reports. 

By  the  alkaline  permanganate  method  forms  of  organic  nitrogen 
are  considered  inferior  in  which  less  than  50  per  cent,  of  the  water- 
insoluble,  organic  nitrogen  is  soluble  in  the  reagent.  By  the 
neutral  permanganate  method,  any  solubility  of  less  than  80 
per  cent,  is  suspicious.  Some  objection  has  been  made  to  the 
method  because  dried  horse  and  sheep  manure,  recognized  as  good 
fertilizers  are  ranked  as  inferior  by  these  methods.  It  is  true  that 
both  have  agricultural  value,  but  this  depends  to  a  considerable 
extent  on  the  favorable  action  in  the  soil  of  the  decomposing 
vegetable  matter,  while  experiment  has  shown  that  the  organic 
nitrogen  in  them  is  less  available  than  in  the  forms  ordinarily  used 
in  the  compounding  of  fertilizers. 

In  the  following  brands  inferior  forms  of  nitrogen  are  indicated 
by  both  methods : 

Regarding  Prices  of  Nitrogenous  Superphosphates. 

The  dealers'  quotation  of  the  cash  ton  price  was  obtained  in 
most  cases  when  each  sample  was  drawn.  These  prices  are, 
however,  no  real  guide  to  prospective  purchasers.  The  manu- 
facturer has  little  or  no  control  over  the  price  which  the  retailer 
or  agent  will  charge  and  the  latter  sells  to  the  consumer  according 
to  special  terms  made  with  him,  which  are  largely  governed  by 
time  of  payment  and  knowledge  of  the  consumer's  financial 
standing  and  habits.  To  take  a  concrete  case:  To-day  a  2-10-0 
formula  can  be  bought  for  $40.    That  is  called  the  "cash  ton  price." 

But  if  paid  for  before  Feb.  i  its  price  will  be  $3  7 ;  if  before  Apr.  i , 
$37.40;  July  I,  $38.00  and  on  Dec.  i,  $40.  If  bought  in  car  lots 
it  will  cost  $1.00  per  ton  less.  If  sold  in  small  fractions  of  a  ton 
the  price  will  be  considerably  higher.  Again,  if  several  dealers 
in  one  place  are  competing  for  trade,  the  quoted  prices  are  likely 
to  be  less  than  where  there  is  no  competition,  or  where  the  dealer 
knows  that  payments  will  be  slow. 

The  general  range  of  prices  is  shown  in  the  following  table :

Analyses  Requiring  Special  Notice. 

8910.  The  American  Ag'l.  Chem.  Co.'s  Complete  Manure  for 
Top  Dressing  19 16  was  found  below  guaranty  in  nitrogen.  A 
second  sample,  9345,  taken  from  a  different  source,  was  analyzed 
with  approximately  the  same  results. 

8909.  The  above  company's  Sure  Growth  Phosphate  being 
somewhat  below  guaranty  in  potash,  a  second  sample,  9344,  of 
this  brand  from  a  different  source  was  found  to  meet  fully  its 
guaranty. 

A  similar  result  appears  in  the  two  analyses  of  Bradley's 
Patent  Superphosphate,  19 16,  Nos.  8977  and  9346. 

9213.  Armotir  Fertilizer  Co.'s  Bidwell's  3-8-1,  having  consider- 
ably less  nitrogen  than  was  guaranteed,  the  manufacturer  re- 
quested the  analysis  of  another  sample,  but  it  was  not  possible 
at  that  time  to  find  the  brand  on  sale  in  the  State. 


NITROGENOUS    SUPERPHOSPHATES.  393 

9032.  Coe-Mortimer  Co.'s  New  Englander  Special  1916,  being 
found  deficient  in  both  nitrogen  and  potash,  effort  was  made 
without  success  to  find  for  analysis  another  sample. 

9405.  National  Extra  High  Grade  Potato  Fertilizer  showed 
deficiencies  in  all  three  ingredients  and  we  were  imable  to  get 
another  sample  from  a  different  source  for  analysis. 

9040.  The  Royster  Guano  Co.'s  Dreadnaught  Fertilizer,  hav- 
ing been  found  deficient  in  potash,  a  second  sample,  9282,  was 
drawn  from  a  different  source,  which  showed  more  potash,  1.86 
per  cent.,  the  guaranty  being  2  per  cent. 

9068.  Quinnipiac  Wrapper  Leaf  Brand  Tobacco  Manure, 
without  Potash,  not  meeting  its  nitrogen  guaranty,  a  second 
sample  was  analyzed,  9319,  which  fully  met  the  guaranty. 

8997.  Rogers  H.  G.  Soluble  Tobacco  Manure  failing  to  meet 
its  guaranty  of  available  phosphoric  acid,  a  second  sample,  9347, 
drawn  from  a  different  source,  was  analyzed  but  agreed  in  compo- 
sition with  the  first  sample.  It  will  be  noticed  that  most  of  the 
superphosphates  without  potash  made  by  this  firm,  while  fully 
meeting  their  guaranties  in  all  other  respects,  fail  to  meet  them  in 
the  one  particular  of  "available"  phosphoric  acid.  The  manu- 
facturer states  that  the  phosphatic  material  used  is  precipitated 
bone  mixed  with  fine  bone  sawings ;  that  the  amotmt  of  available 
phosphoric  acid  found  in  these  materials  when  separately  analyzed 
should  yield  fully  the  amount  guaranteed  in  the  mixture  of  them ; 
but  that  this  is  not  the  case  and  that  there  are  large  discrepancies 
between  the  analyses  of  mixtures  of  these  two  ingredients  reported 
by  different  trade  chemists.  Examination  of  the  bone  used  shows 
the  presence  of  a  considerable  amount  of  carbonate  of  lime.  The 
presence  of  carbonates,  we  believe,  in  any  fertilizer  is  likely  to 
reduce  the  amount  of  "available"  phosphoric  acid  found  by  the 
official  method.  The  precipitated  bone,  whether  alone  or  mixed 
with  carbonates,  is,  we  believe,  readily  available  to  crops. 

9225.  Royster's  Curfew  Ammoniated  Superphosphate  having 
failed  to  meet  its  nitrogen  guaranty,  a  second  sample,  9348,  drawn 
from  a  different  source,  was  analyzed  and  substantially  met  the 
nitrogen  guaranty.  The  same  thing  was  found  in  Royster's 
Good  Will  Ammoniated  Superphosphate,  Samples  9228  and  9404. 
8907.  In  Sanderson's  H.  G.  Ammoniated  Phosphate  the 
available  phosphoric  acid  was  below  guaranty  but  in  two  other 
samples  of  the  same  brand,  9075  and  9308,  this  guaranty  was 
fully  met.

These  dried  manures  are  chiefly  of  interest  to  florists  and  to 
greenhouse  or  lawn  owners.  As  we  have  said  in  previous  reports, 
they  are  out  of  the  question  for  general  farm  use,  because  horse 
manure  supplies  three  or  four  times  as  much  plant  food  for  the 
same  money,  and  the  extra  vegetable  matter  should  be  supplied  in 
farm  crops  and  residues. 


WOOD    ASHES.  417 

WOOD  ASHES. 

Twenty  samples  called  "wood  ashes"  were  analyzed.  Three  of 
these,  8862,  8811  and  8698,  have  the  character  of  lime-kiln  ashes 
and  contain  very  little  potash.  The  remaining  samples  are  good, 
bad  or  indifferent.  Nine  samples  contained  from  4.7  to  6.8  per 
cent,  of  potash;  four  from  2.8  to  3.7  per  cent.,  and  four  from  0.8 
to  1.7  per  cent. 

The  prices  were  exceedingly  variable ;  for  instance,  $9.00  per  ton 
for  material  containing  2.8  per  cent,  of  potash;  $16.00  for  ashes 
containing  1.5  per  cent,  and  $27.50  for  one  containing  4.72  per 
cent.  Certain  of  the  higher  grades  were  sold  on  the  unit  basis,  the 
price  ranging  from  $4.50  to  $6.00  per  unit  of  water-soluble  potash. 

The  extreme  variability  in  the  potash  content  of  wood  ashes 
emphasizes  the  necessity  of  always  buying  it  on  a  definite  guaranty 
of  water-soluble  potash. 

Only  three  of  the  samples  were  accompanied  by  a  guaranty, 

9372,  9025  and  8862.   These  were  guaranteed  2.00,  5.03  and  3.00 

per  cent,  of  potash,  respectively,  and  contained  1.50,  4.72  and 

0.07  per  cent. 

HOUSEHOLD  WASTES. 

At  the  present  time,  when  the  prices  for  potash  fertilizers  are 
almost  prohibitive,  any  available  source  of  this  important  element 
is  a  matter  of  interest.  Possibly  few  householders  realize  the 
fertilizer  value  of  many  of  their  household  wastes  which  they 
usually  throw  away.  The  actual  content  of  potash  in  any  of  these 
is  small,  but  may  be  worth  saving. 

The  samples,  whose  analyses  are  given  in  the  accompanying 
table,  were  for  the  most  part  prepared  by  Prof.  P.  E.  Browning, 
of  Yale  University,  and  submitted  by  him  to  us  for  analysis.  It 
is  to  be  regretted  that  the  actual  percentages  of  ash  were  not  de- 
termined, as  the  information  thus  supplied  would  have  been 
valuable.  The  results,  however,  are  suggestive,  and  indicate 
how  much  valuable  fertilizer  material  in  the  aggregate  is  thrown 
away  by  the  American  public.  Many  of  these  ashes  could  be 
prepared  in  the  ordinary  open  fireplace  of  the  average  home  and 
could  be  collected  with  the  ashes  from  the  wood  there  burned. 
The  citrus  fruit  skins,  because  of  their  oil,  burn  readily,  and  our 
analyses  show  how  rich  in  potash  their  ashes  are.  The  analyses  also 
suggest  the  utility  of  community  incinerating  plants  as  a  means 
of  conserving  the  important  amounts  of  potash  which  some  house- 
hold wastes  contain.

The  two  commercial  samples  contain  much  more  mineral  matter 
and,  consequently,  less  vegetable  matter  than  four  of  the  samples 
from  local  deposits.  It  will  be  noted  that  9062  contains  less  of  all 
the  ingredients  claimed  except  mineral  matter,  containing  only 
two-thirds  of  the  nitrogen,  one-twentieth  of  the  phosphoric  acid 
and  one-fifth  of  the  potash  claimed.
